Application-Decemberliix, 1941, Serial No. 423,?:2-9 1 claim. (o1.ietf-:i (Granted under the eet of March a 1883,- :as

amended April 30, 1928; 370 0. G. 757) The invention described hereinmay be manufactured and used by or for the Government for governmentalpurposes, without the payment to me of any royalty thereon.

This invention relates to a projectile container and in particular to asupport for the ogival end thereof.

In the handling, storing and shipping of projectiles having delicateparts it is necessary to pack each shell in a separate container. Thepacking at the ogival end requires special attention for two mainreasons: rst, the point must be secured in spaced relation from thecontainer or mutilation of the latter will result, and second, the pointusually bears the delicate elements of the shell whether a mechanicalfuse, a windshield or any plain ogive other than a hardened point.

Heretofore, m one example of actual practise, the ogive has beensupported by inserting within the container a short sleeve, sliding a U-shaped member through slots in the cap designed to receive a Spannertool and resting the U- shaped tool on the top of the sleeve. Thisarrangement presented many diiculties due to highly concentratedstresses. It was found that the member would yield at the point ofsupport in the Spanner slots and even if hardened would fracture.Likewise the stresses at the point of support on the sleeve beingconcentrated, the sleeve, being made of wood, tended to yield. Inaddition to these dilculties, the U-shaped member was heavy andexpensive. The present invention overcomes these diiculties as pointedout hereinafter.

It is therefore an object of the invention to provide a support for theogive in a projectile container which shall be light, easy andinexpensive to manufacture, and which shall afford an even distributionof stresses.

To these and other ends, the invention consists in the construction,arrangement and combination of elements described hereinafter andpointed out in the claim forming a part of this specication.

A practical embodiment of the invention is i1- lustrated in theaccompanying drawing wherein:

Fig. 1 is a partial elevational view in axial section of a containerwith a projectile in place.

Fig. 2 is a top plan View of the ogive support of Fig. 1.

Fig. 3 is an elevational view of the support shown in Fig. 2.

Fig. l is an elevational View, shown partly in axial section, of amodification of the ogive support, and

Fig. 5 is a view similar to Fig. 4, showing a further modication of theogive support.

Fig. 6 is a top plan view of a modification of an ogive support.

Figure 7 is a fragmentary sectional view of the supporty showing moreclearly the relation between the metallic annulus and the interior ofthe sleeve.

Referring to the drawing by characters of reference, there is shown inFig. 1 a cylindrical container I preferably of rolled paper or cardboardbut which may consist of any suitable material and which may be closedoff by a metal bottom such as 2. The particular form and material of theouter container itself forms no part of the present invention. Nestedwithin the container and resting on the bottom is a short sleeve 3 ofwood or paper or any suitable material and which may be secured in placeas by nails 4 or by gluing or any suitable attaching means. Resting onthe crown of the sleeve 3 is a metallic annulus 5 with its centralportion 6 depending downward on a slant adapted to accommodate a portionof a projectile ogive 1. 'I'he inner rim may be further bent away fromthe ogival curve as shown at 8. This will further strengthen thesupporting zone by reason of making contact With the sleeve. The annulus5 may be attached to the crown of the sleeve 3 as by tacks 9 or othermeans or may be left loose, in which case it can be withdrawn with theprojectile and subsequently removed Without diillculty.

The annulus with depending inner surface provides a support which dwellson all available area of the sleeve crown and thus permits the use of asofter and hence cheaper material for the sleeve, such as paper, as wellas affording a maximum of surface contact with the projectile tominimize local stresses. The main stresses will be located in a circularzone and can be readily withstood in even a very thin member. Theannulus should be supported by the sleeve 3 up to the point of the bend.

Although it might seem probable that binding would occur between a heavyprojectile and a metal support no serious dilculties have beenencountered on this score. However, such a posy sibility may be obviatedby providing a lining for the support such as canvas l0 shown in Fig. 4.This is shown as having scallops Il to adapt a a dish-shaped blank tothe depending portions of the support, but a `simple annulus of thelining may be adapted without such modiiication. Any non-metallicmaterial may be used for the lining, the purpose being merely to avoidthe interlocking of metal surfaces, and the lining may be attached inany convenient manner as by gluing or stapling.

To avoid possible laceration of the sides of the container, the supportmay have its outer end upturned as shown at I2 in Fig. 5.

While the annular support has been described as preferably metallic, itwill be understood that the particular material used is not to be deemedused. The supporting member shown in Fig. 6,y

for instance, is adapted for use with a square container.

I claim:

A projectile container comprising an outer housing, an inner sleeveengaging the inner wall of the housing and shorter than the housing andlocated at one end thereof, anda support for the projectile ogivecomprising a ilat portion located on and covering a substantial area ofthe end portion of said sleeve and having a central flange dependingbelow the level of saidilat portion and dening between said flat portionand said ilange an inwardly inclined surface adapted to receive theogive portion of a projectile, the lower end of said flange beingprovided with an outturned flange in engagement with the inner wall ofthe sleeve to support the lower end of said flange.
